Abstract
The utility model relates to a teaching instrument, specifically relates to a demonstration device passing through a wall and aims to realize stable operation and obvious teaching effects. According to a technical scheme, the demonstration device passing through the wall comprises a foundation (1), a support (2), a hollow tube (3) and a ball body (4), wherein two ends of the hollow tube are sealed, the hollow tube is prepared by a transparent material, one side of the support (2) is fixedly connected with the foundation (1), the other side of the support (2) is hinged with a central portion of the hollow tube (3), the ball body (4) is arranged in the hollow tube (3), and an inner wall of the hollow tube (3) is provided with polarization films. The demonstration device is characterized a number of the polarization films is multiple, two ends of the hollow tube (3) are horn-shaped structures, and a lower bottom face of the foundation (1) is provided with multiple suckers (5).
Description
Technical field
The utility model relates to a kind of instruments used for education, specifically refers to a kind of wall-penetrating Demonstrator.
Background technology
So-called wall-penetrating Demonstrator is being commonly called as of Experiments of Optics instruments used for education, principle is the difference by printing opacity direction between the polaroid, so that visually produce a baffle plate that can not pass, and this baffle plate does not exist in the reality, bead can pass the so-called baffle plate of this face in experiment, thereby reach the experimental apparatus of proof polarisation of light principle by this phenomenon, a kind of wall-penetrating Demonstrator of prior art, it comprises base 0.1, support 0.2, sealed at both ends hollow tubular 0.3 and spheroid 0.4; One end of described support 0.2 is fixedly connected with base 0.1, the other end and the middle part threaded engagement of hollow tubular 0.3, described spheroid 0.4 is positioned at hollow tubular 0.3, the left-half inwall of described hollow tubular 0.3 is provided with the first polarizing coating; The right half part inwall is provided with second polarizing coating, the printing opacity direction of described the first polarizing coating and the second polarizing coating can not be identical, such structural design so that product see from the outside, a baffle plate is arranged in the middle of the hollow tubular 0.2, actual this baffle plate is non-existent, because polarisation of light phenomenon produce an effect, when using this demonstrator, raise an end of hollow tubular 0.3, spheroid 0.4 can pass this baffle plate easily, a kind of as wall-penetrating Demonstrator, prior art has the following disadvantages: instrument stabilizer when in use demonstration instrument for teaching can not guarantee to operate, because of a baffle plate that only has two polarizing coatings visually to form, teaching efficiency is not obvious simultaneously.
The utility model content
The technical problems to be solved in the utility model is, a kind of obvious wall-penetrating Demonstrator of teaching efficiency that also reaches when instrument stabilizer when guaranteeing to operate is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of wall-penetrating Demonstrator, and it comprises base, support, sealed at both ends hollow tubular and spheroid; One end of described support is fixedly connected with base, the middle part threaded engagement of the other end of described support and hollow tubular, and described spheroid is positioned at hollow tubular, and the inwall of described hollow tubular is provided with polarizing coating; It is characterized in that: described polarizing coating quantity is a plurality of, and the two ends of described hollow tubular are horn-like, and described base bottom surface is provided with a plurality of suckers.
After adopting above structure, the utlity model has following advantage: described polarizing coating quantity is a plurality of, and described a plurality of polarizing coating printing opacity direction adjacent one another are is mutually vertical, can visually form the existence of a plurality of baffle plates, can see more intuitively that at Students in Teaching polaroid is to the effect of light, the two ends of described hollow tubular are horn-like simultaneously, can there is no true catch existence the described hollow tubular so that the student more obviously finds out from two ends, thereby it is obvious to reach teaching efficiency; Because described base bottom surface is provided with a plurality of suckers, can make base keep stable, the stable effect of instrument state when having guaranteed operation.
As improvement, it is a row that the quantity of described sucker is nine and per three, and such arranges so that more reliable the fixing with desktop in domain.
As improvement, the upper surface of described base is provided with one deck flexible material.Hollow tubular is being carried out an end when too high, can prevent because the excessive other end of hollow tubular and the base of causing of exerting oneself collides, so that hollow tubular is damaged.
Description of drawings
Fig. 1 is the structural representation of the wall-penetrating Demonstrator of prior art.
Fig. 2 is the structural representation of wall-penetrating Demonstrator of the present utility model.
As shown in the figure: prior art: 0.1, base, 0.2, support, 0.3, hollow tubular, 0.4, spheroid.
The utility model: 1, base, 2, support, 3, hollow tubular, 4, spheroid, 5, sucker.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
By reference to the accompanying drawings 2, a kind of wall-penetrating Demonstrator, it comprises base 1, support 2, sealed at both ends hollow tubular 3 and spheroid 4; One end of described support 2 is fixedly connected with base 1, the middle part threaded engagement of the other end of described support 2 and hollow tubular 3, and described spheroid 4 is positioned at hollow tubular 3, and the inwall of described hollow tubular 3 is provided with polarizing coating; Described polarization film quantity is a plurality of, because the printing opacity direction between the polarization film can not be in full accord, so will inevitably occur one between polarizing coating visually exists and non-existent catch in fact also, the two ends of described hollow tubular 3 are horn-like, and described base 1 bottom surface is provided with a plurality of suckers 5; It is a row that the quantity of described sucker 5 is nine and per three; The upper surface of described base 1 is provided with one deck flexible material.
Above the utility model and embodiment thereof are described, this description does not have restricted, and shown in the accompanying drawing also is one of embodiment of the present utility model, and actual structure is not limited to this.If generally speaking those of ordinary skill in the art is enlightened by it, create aim in the situation that do not break away from the utility model, without the creationary frame mode similar to this technical scheme and the embodiment of designing, all should belong to protection domain of the present utility model.
